Correlation analysis between neck muscles and lifestyle habits in patients with cervical instability.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe neck muscles play a crucial role in maintaining cervical spine stability. A thorough understanding of the changes in neck muscles during cervical instability (CI), along with an analysis of their correlation with lifestyle habits, can provide valuable data for the prevention and treatment of CI.
methodsA total of 98 patients with CI and 88 healthy subjects were included in the study. Their cervical MRI images and lifestyle habits information were collected. The relative cross-sectional area (RCSA) and fat signal fraction (FSF) of the neck muscles were obtained from the MRI images. Correlation analysis was conducted between the muscle parameters, CI, and lifestyle habits information.
resultsCI subjects spent more time working (P =.026) and using computers daily than the healthy subjects (P =.023). The cervical curvature of the CI subjects was significantly smaller compared to healthy subjects (P =.004). CI subjects had significantly smaller RCSA (P =.003) and greater FSF (P =.011) in the deep muscles at the back of the neck compared to healthy subjects. FSF in the deep muscles at the back of the neck (OR = 2.343, 95%CI = 1.261-4.352) and cervical curvature (OR = 0.904, 95%CI = 0.848-0.965) were risk factors for CI. Keeping head down time per day (r = - 0.286) and using the computer time per day (r = - 0.230) were negatively correlated with the RCSA in the deep muscles at the back of the neck.
conclusionsChanges in the deep muscles at the back of the neck are key factors in the development of CI. Prolonged maintenance of a single downward head posture is closely related to changes in the deep muscles at the back of the neck.
